stephen long realized the importance of stiffness in a bridge, the need for everything to be tight andss. and he worked out the basic geometry we find in the howe truss, but because wrought iron was not very common in 1830, stephen long built his truss using wood for the verticals. william howe advocated replacing the timber verticals with wrought-iron rods that could be more quickly installed and more easily adjusted later. there's only so many trusses that people invented that really work. the bridges that are surviving now are generally pretty good ones. most people realize that the trusses hold a bridge up, but the purpose of the bridge's covering is less obvious. just exactly why are these bridges covered? wow, you know, that is a good question. i understand that back in the olden days, that's where they took cover when it rained, with the buggies. um, maybe so they wouldn't be slippery for when it snows? oh... i haven't the slightest idea. [ laughs ] the cover covers over the people so they don't get all wet from the rain, say, or the snow. probably to keep the rain off you -- i

the midwest, beijing can argue it is helping to bring economic renewal to a region long plagued by a decline." stephen, a tampa, florida, you are on the air. caller: the whole idea of free labor and a slave labor they have in china. slave labor costs 1/20 of free labor. of course these american companies are going to take advantage of these poor people's plight and send all of our jobs over there. i think the president is wrong, and as soon as the american people understand why we are losing jobs, why all the buildings are being built in china, people will send him and bring us new leaders. host: nancy benec, this is an important issue for the white house. yesterday we heard from robert gibbs talking about tough talk the president will have with the chinese leader. why is that? guest: well, the president knows that china is a huge growing economy, and for the health of the u.s. economy, we need to engage with them and tap into those markets. after the bilateral meetings at the oval office today, there will be a larger meeting at the white house with the president brings in a lot of the u.s. corporate

regions the rest was inspired by the months long chaos in tunisia where uprising saw its needed to post eighty dead and a cabinet reshuffle political scientist dr stephen which says the turmoil could spell trouble not just for north africa but for europe. well if everything breaks apart and particularly in the french speaking north africa that could lead to massive waves of immigration and that is a worry for europe especially of the european countries in the northern shores of the mediterranean spain and france and italy but the france would be the major part of this nation for these waves of immigrants because most of them also have some friends they speak french after all these countries were part of the former french empire and they're also in france a lot of arabic speaking population and so if any country who is extremely worried about this or could be worried about it is grand. as the clashes in north africa continue ati's alexy has cesky reports now on how they bear some striking parallels with elsewhere. george year two thousand and three. and ukraine two thousand four. cutest on two thousand and five. and egypt twenty eleven i think these are

island sound, due to long island and the british will welcome you with open arms and you'll find yourself among friends. so hundreds of people go across, and one of them is stephen. when he gets there, steven jarvis in lists and the americas -- i'm sorry, the queens rangers. queens rangers is one of 150 or more, at least 150 military units formed i tories, to fight, not just debate, fight other americans who are rebels. and if you follow stephen's journal, one of the first remark will things about it is the journal is called an americans experience in the british army. he's not in the british army. he's in a tory army unit that was formed by tories in new york, and he will fight alongside or independent of the british army. but it's not the british army. but just like what happened with tiffany's manuscript, the manuscript for jarvis is a journal was found in a trashcan and published in 1907. in 1907, we didn't want to think of the revolution as anything but the revolution. and we couldn't use the term civil war because we had had a north-south real civil war only a generation before. so the whole term civil war kind of goes away, and so does the idea of tories.

stephen colbert or jon stewart. >> colbert and stewart are the most trusted men? wow. we have really come a long way. really come a long way. well, my point is that in those days, anyway cronkite represented legitimacy and respectability and solid news. at the same time, when i arrived at the cbs bureau in washington, we had one woman reporter, two women editors and two women producers. today, poo. it's way over 50%. it's a totally changed environment but in those days it was very much a man's world. no question about that. and the people at the very top right now two of the three top evening anchors are women. so that in and of itself gives you a demonstration of the change. so we have come a long way from then, but then, time and time again i think the reporting was much sounder. let me give you one illustration. cbs had a marvelous reporter named winston burrdett. no longer with us. winston covered italy. he covered the vatican. and it was his responsibility every now and then to wander off into the middle east. one day, at the state department i got a call from our washington bureau chief, terrif

secrets for a very very long time this would be the best kept secret probably in the history of national security across the world. i have a quote a scientist from the united kingdom stephen hawking it says that advanced extraterrestrial life could conquer and colonize there actually what way thinking about what we're dreaming up to to to find a contact with somebody. if it happens it may be the end of our civilization do you believe in that. again that's that's sheer speculation but. you. a truly advanced society would probably have little need of earth so i could it would seem like worth their time to become used to it but that's just speculation so you think they've been there if they have a possibility they have the resources to come to see whatever they would be interested in this planet yeah well i think first of all you have to realize that communicating from one planet to another is extremely difficult and that is something that and that is something that we know how to do at the speed of light actually transporting any. body from any mass from one solar system to another is extraordinarily difficult so that the the value added to even go in the first place much l
